[julia-users] Re: How to get first number from Int64

If you do a: precomp = map(log10,2:10) Then a oneliner for the first digit is: searchsortedfirst(precomp, log10(lista[3])%1.0) There are many paths in the garden. But this one is not as long (slow) as it looks. On Tuesday, October 27, 2015 at 10:35:18 AM UTC+2, Alireza Nejati wrote:

[julia-users] Deprecation warnings using julia on Atom

Hi all, I'm using Julia v0.4 with the Atom package, on Atom 1.0 with the packages ink, julia-client, and language-julia (and I'm really enjoying this as an IDE solution). I can toggle the Julia console in Atom, and enter code directly into it without any errors or warnings. However, as soon as

[julia-users] Re: [Gadfly] : Help regarding plotting

The design philosophy of Gadfly seems to be that you should think about the data and let the software worry about how to present it. That said, it is possible to change things like fonts, line thicknesses and dash styles, and legend placement through themes: http://gadflyjl.org/themes.html Mor

Wow, I'm glad there's been such a positive response! I meant every word and more. I too have a publication coming up soon (albeit not in Nature -- which is beyond awesome) and Julia is referenced there. As it will probably be in every publication I have from now on. Thanks again! On Wednesday,

[julia-users] Inconsistent behaviour of round()

Hi there, I'm using Julia 0.4.0. round(4.5) gives 4.0, i.e. it rounds down. round(5.5) gives 6.0, i.e. it rounds up. Any ideas why this is the case? Cheers, Jock

Re: [julia-users] Deprecation warnings using julia on Atom

Ah... understood. Many thanks. I'm afraid I'm still not getting the desired result however. After running checkout on "Atom", "CodeTools" and "JuliaParser" I run Pkg.status() and can verify I'm on the master branch for all 3. So I fire up Atom again, try to evaluate in the editor, and get the f

Re: [julia-users] ESS and autocompletion for Julia

Does tab completion work in other languages supported by ESS? If it doesn't then there would appear to be something missing from your ESS settings (I don't bind completion to TAB myself, there is too much already happening on the TAB key). If it works for (e.g.) R but not Julia I would report a bug

You’re running into another known issue: https://github.com/JuliaLang/julia/issues/12941 Try opening a normal REPL in the terminal and run “using Atom” to trigger the precompilation, then it shouldn’t need to happen when you run from Atom. -s
